Multi-spectral camouflage : ウィキペディア英語版 | Multi-spectral camouflage
Multi-spectral camouflage is the use of counter-surveillance techniques to conceal objects from detection across several parts of the electromagnetic spectrum at the same time. While traditional military camouflage attempts to hide an object in the visible spectrum, multi-spectral camouflage also tries to simultaneously hide objects from detection methods such as infrared, radar, and millimetre-wave radar imaging. Among animals, both insects such as the eyed hawk-moth, and vertebrates such as tree frogs possess camouflage that works in the infra-red as well as in the visible spectrum. ==History==
The English zoologist Hugh Cott, in his 1940 book ''Adaptive Coloration in Animals'', wrote that some caterpillars such as the eyed hawk-moth ''Smerinthus ocellatus'', and tree frogs such as the red-snouted treefrog ''Hyla coerulea'', are coloured so as to blend with their backgrounds whether observed in visible light or in infra-red. Cott noted the importance of camouflage in the infra-red, given the ability of tactical reconnaissance to observe in this part of the spectrum: A German-led NATO research project concluded in 2004 that while "the multispectral signatures of most military equipment can be significantly reduced by combinations of various camouflage materials", multi-spectral camouflage for individual soldiers remained lacking. The main problems identified were operational constraints such as mobility, weight, and the soldier's physiology.〔(【引用サイトリンク】url=http://www.cso.nato.int/Pubs/rdp.asp?RDP=RTO-TM-SCI-096 )〕
